Abstract:
This document specifies a CBOR encoding of X.509 certificates. The
resulting certificates are called C509 Certificates. The CBOR
encoding supports a large subset of RFC 5280 and significantly
reduces the size of certificates compatible with e.g. RFC 7925, IEEE
802.1AR (DevID), CNSA, and CA/Browser Forum Baseline Requirements.
When used to re-encode DER encoded X.509 certificates, the CBOR
encoding can in many cases reduce the size of RFC 7925 profiled
certificates with over 50%. The CBOR encoded structure can
alternatively be signed directly ("natively signed"), which does not
require re-encoding for the signature to be verified. The document
also specifies COSE headers as well as a TLS certificate type for
C509 certificates.
NOTE: "C509" is a placeholder, name to be decided by the COSE WG.
